Frequently Asked Questions
For most people, yes. Merino breathes, regulates temperature and resists odour, so one set lasts a multi-day trip and doubles as sleepwear. Synthetic polypro, like XTM's Heatflex, costs less, dries faster and has Polygiene odour control. Many people ski in merino and keep a Heatflex set as a spare.
For Australian resorts, a 200 to 230 gsm merino top and pants suits most days. For January in Japan, choose 230 gsm, such as XTM's Merino 230 or Alpine 230, and layer a fleece on top when it is very cold. A 170 gsm thermal suits travel and mild days.
Fine merino is soft on the skin. XTM's Active200 uses 18.5 micron merino and Ottie Merino uses 18.4 micron superfine merino. Lower micron numbers feel softer. If you have very sensitive skin, try a merino top for a day around the house before your trip.
How to choose thermals
• Merino or polypro: merino regulates temperature and resists odour, so you can wear it for days. XTM'sHow to choose thermals
• Merino or polypro: merino regulates temperature and resists odour, so you can wear it for days. XTM's Heatflex top is 180 g/m² polypro with Polygiene odour control: it dries fast and costs less.
• Weight: 170 gsm (Adventure170) is a light layer for travel, 200 to 210 gsm (Active200, Ottie Merino) a midweight for active days, and 230 gsm (XTM Merino 230 and Alpine 230) the warmest merino we stock.
• Fit: a thermal only works close to the skin, so choose a snug fit, not a loose one.
• Pants: full length for walking and sleeping, or 3/4 length to stop above a ski boot.
Shop thermals by fit
• Men's thermals: XTM Merino 230, Active200 and Valentino tops and pants, Ottie Merino, plus sizes to 7XL.
• Women's thermals: XTM Alpine 230, Merino 230 and Active200, Ottie Merino, and plus size Adventure170 tops.
• Kids thermals: XTM Alpine230 merino and Heatflex polypro tops and pants.
• By brand: XTM Performance and Ottie Merino.
Ski thermals for Japan and the Aussie Alps
A ski trip to Niseko or Hakuba in January means long lift days in dry cold. Wear a 230 gsm merino top and 3/4 pants under your ski gear, and add a fleece on the coldest days rather than a thicker thermal. In the Aussie Alps season, June to September, a 200 gsm set handles most days. Finish with ski socks and snow gloves.
